(1) Overview Each drawing described in the following embodiments is a schematic drawing, and the size and thickness ratios of each constituent element in each drawing necessarily reflect the actual dimensional ratio. Not necessarily.

The detector 1 according to the present embodiment detects that an event that is a target of disaster prevention has occurred. Further, the detection system 100 according to the present embodiment includes a plurality of detectors 1 as shown in FIG. Further, the detector management system 200 according to the present embodiment includes a detection system 100 and an external terminal 5 that manages the plurality of detectors 1 as shown in FIG. 1.

Here, as an example, it is assumed that the event targeted for disaster prevention is a fire. That is, it is assumed that the detector 1 is a fire detector. In particular, the detector 1 has a detection function for detecting the occurrence of a fire and an alarm function for giving an alarm when the occurrence of the fire is detected. There is). The detector 1 outputs a sound such as an alarm sound when a fire occurs, for example. However, the event subject to disaster prevention is not limited to fire, and may be water damage, an earthquake, or the like. Further, the event subject to disaster prevention may be gas leakage, generation of CO (carbon monoxide) due to incomplete combustion, or the like.

The detector management system 200 is applied to the facility 7 (see FIG. 2), for example. Specifically, the plurality of detectors 1 are installed on a ceiling, a wall, or the like in the installation target space in the facility 7. In the present embodiment, the plurality of detectors 1 are installed in the spaces E1 to E5 in the facility 7, respectively, as shown in FIG. The external terminal 5 of the detector management system 200 is, for example, a controller of a HEMS (home energy management system) installed in the facility 7.

As described above, it is assumed that the detector 1 is, as an example, a live alarm and the facility 7 is a detached house. However, the facility 7 may be an apartment house (condominium). Furthermore, the facility 7 is not limited to a residence, but is a non-residential facility such as an office building, a theater, a movie theater, a public hall, a playground, a complex, a restaurant, a department store, a school, a hotel, an inn, a hospital, a nursing home, a kindergarten, It may be a library, a museum, an art gallery, an underground mall, a station, an airport, or the like.

Here, in the present embodiment, as shown in FIG. 1, the detector 1 includes a holding unit H1 that holds at least location information related to the installation location L1 (see FIG. 2) where the detector 1 is installed. .. The installation location L1 corresponds to any of the spaces E1 to E5 in the example of FIG. The holding unit H1 corresponds here to the storage unit 20 that stores the location information as data. Specifically, the holding unit H1 is composed of a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like. However, the holding unit H1 is not limited to being configured by the above device. The holding unit H1 may hold the location information by switching ON/OFF states of contacts such as a DIP switch or a rotary switch.

In the following, as an example, when the detector 1 functions as a child device, the location information held by the holding unit H1 is information related only to the installation location L1 of the detector 1 itself (own device). In other words, the holding unit H1 of the child device holds only the place information related to the installation place L1 of the own device, and holds the place information related to the installation place L1 of another detector 1 (another device). Not yet. On the other hand, when the detector 1 functions as a parent device, the detector 1 holds not only the place information related to the installation place L1 of the own device but also the place information related to the installation place L1 of another device. And

According to this configuration, the holding unit H1 holds the location information. Therefore, for example, when the detector 1 itself gives a notification according to the location information, or when another device gives a notification according to the location information of the detector 1, an event (for example, a fire) targeted for disaster prevention. It is possible to improve the recognizability of the place where the) occurs.

(2) Details (2.1) Overall Configuration Hereinafter, the overall configurations of the detector 1, the detection system 100, and the detector management system 200 according to the present embodiment will be described in detail. Here, the detector 1 is, for example, a battery-powered resident alarm device. However, the detector 1 may be electrically connected to an external power source (for example, a commercial power system), and may be driven by converting AC power (for example, effective value 100V) supplied from the external power source into DC power.

The detection system 100 includes a plurality of (five in the illustrated example) detectors 1 as shown in FIGS. 1 and 2. The plurality of detectors 1 is a so-called interlocking type of resident alarm, and even if any of the detectors 1 detects a fire, it interlocks with the other detectors 1 (along with the other detectors 1) and outputs an alarm sound. Is configured to issue an alert. In this embodiment, a communicable network is formed between the plurality of detectors 1. Here, of the five detectors 1, the detector 1A functions as a master unit, the other detectors 1B to 1E function as slave units, and communication is possible between the master unit and the slave unit (FIG. 2). Hereinafter, the four detectors 1B to 1E that function as slaves will be referred to as slaves 101 (first detectors), and the detector 1A that functions as a master will be referred to as masters 102 (second detectors). Sometimes.

In the following, as in the example of FIG. 2, it is assumed that all of the plurality of detectors 1 are installed on the ceiling surface of each room or stair in the facility 7 (a detached house). Specifically, the detector 1A is arranged in the space E1, the detector 1B is arranged in the space E2, the detector 1C is arranged in the space E3, the detector 1D is arranged in the space E4, and the detector 1E is arranged in the space E5. The space E1 is, for example, a living room. The space E2 is, for example, a bedroom. The space E3 is, for example, a staircase. The space E4 is, for example, a children's room. The space E5 is, for example, a kitchen. In the example of FIG. 2, a fire is occurring in the living room space E1. Details of each detector 1 will be described later in the section “(2.2) Detector”.

The detector management system 200 includes a detection system 100 and an external terminal 5, as shown in FIG. The detector management system 200 may further include the information terminal 6 and the external server 8 (see FIG. 3). The external terminal 5 is configured to manage the plurality of detectors 1. In the example of FIG. 2, the external terminal 5 is installed beside the stairs on the first floor in the space E3. Details of the external terminal 5, the information terminal 6, and the external server 8 will be described later in the section “(2.3) External terminal”.

(2.2) Detector (2.2.1) Base unit (second detector)
First, the configuration of the master device 102 (detector 1A) among the plurality of detectors 1 will be described.

The main|base station 102 is comprised so that the event (here, fire) which becomes the target of disaster prevention may be detected. The main|base station 102 has the detection function which detects the occurrence of the fire in the facility 7, and the alarm function which alerts when the occurrence of the fire in the facility 7 is detected. As shown in FIG. 1, the main|base station 102 is equipped with the control part 10, the memory|storage part 20, the 1st communication part 21, the 2nd communication part 22, the battery 23, the detection part 3, and the alerting|reporting part 4. In addition to this, the parent device 102 further includes circuit modules such as an acoustic circuit and a lighting circuit. The battery 23 is, for example, a lithium battery, and the parent device 102 operates by electric power supplied from the battery 23.

The parent device 102 also includes a holding unit H1 that holds at least location information related to the installation location L1 where the detector 1 is installed. As described above, the holding unit H1 corresponds to the storage unit 20 as an example. Further, the holding unit H1 of the parent device 102 holds not only the location information related to the installation location L1 where the own device is installed, but also the location information associated with each installation location L1 of the four child devices 101.

The control unit 10 has a computer system having a processor and a memory, for example. Then, the computer system functions as the control unit 10 by the processor executing the program stored in the memory. The program executed by the processor is previously recorded in the memory of the computer system here, but may be provided by being recorded in a recording medium such as a memory card or through a telecommunication line such as the Internet. ..

The detection unit 3 has a function (detection function) of detecting information about a fire that is a target for issuing an alarm sound. Here, the detection unit 3 is, for example, a photoelectric sensor that detects smoke. Therefore, the above-mentioned information about fire includes information about smoke, for example. However, the detection unit 3 is not limited to the photoelectric sensor, and may be, for example, a constant temperature sensor that detects heat. As shown in FIG. 1, the detection unit 3 includes, for example, a light emitting unit 31 such as an LED (Light Emitting Diode) and a light receiving unit 32 such as a photodiode. The light emitting unit 31 and the light receiving unit 32 are arranged such that the light receiving surface of the light receiving unit 32 deviates from the optical axis of the irradiation light of the light emitting unit 31 in the labyrinth of the housing of the own device. In the event of a fire, smoke may be introduced into the labyrinth through holes provided in the housing.

When there is no smoke in the labyrinth of the housing, the irradiation light of the light emitting unit 31 hardly reaches the light receiving surface of the light receiving unit 32. On the other hand, when smoke is present in the labyrinth of the housing, the irradiation light of the light emitting unit 31 is scattered by the smoke, and a part of the scattered light reaches the light receiving surface of the light receiving unit 32. That is, in the detection unit 3, the light receiving unit 32 receives the irradiation light of the light emitting unit 31 scattered by the smoke. The detector 3 outputs to the controller 10 an electric signal (detection signal) indicating a voltage level corresponding to the amount of light received by the light receiver 32.

As shown in FIG. 1, the notification unit 4 has a display unit 41 and a sound unit 42. The notification unit 4 has a function (notification function) of notifying the occurrence of the fire when the occurrence of the fire in the facility 7 is detected. In the present embodiment, the notification unit 4 performs notification by light and sound.

The sound section 42 has a function of reporting the occurrence of fire. The acoustic unit 42 outputs a sound (sound wave). When the control unit 10 determines that a fire has occurred in the facility 7, the sound unit 42 outputs an alarm sound to notify the occurrence of the fire.

The acoustic unit 42 is composed of a speaker that converts an electric signal into sound. The speaker has a diaphragm, and emits an alarm sound by mechanically vibrating the diaphragm according to an electric signal. The sound unit 42 outputs an alarm sound (for example, a “beep” sound) under the control of the control unit 10. It is preferable that the sound section 42 change the loudness (sound pressure level) of the warning sound and output the warning sound. The alarm sound may include, for example, a sweep sound that is swept from a low sound to a high sound.

However, the alarm sound of the present embodiment is output under the control of the control unit 10 by including at least the location information related to the installation location L1 of the detector 1 that has detected the fire in the voice message. In other words, the notification unit 4 of the present embodiment, when detecting the occurrence of a fire (event), gives notification according to the detected location information of the detector 1. The "location information" related to the installation location L1 is name information indicating the name of the installation location L1 ("living room", "stairs", "bedroom", "child's room", "kitchen", etc.), or the installation location. It is code information (“A1”, “A2”, “A3”, etc.) for identifying L1. Here, the alarm sound is output by including the name information in the voice message. The alarm sound is composed of a sweep sound and a voice message following the sweep sound.

The installation place L1 of the parent device 102 is a living room (space E1). If the occurrence of a fire is detected by the master device 102, the acoustic unit 42 of the master device 102 outputs a voice message such as "A fire in the living room. A fire in the living room." In this case, with respect to the interlocking operation of the alarms among the plurality of detectors 1, the alarm interlocking source (fire origin) is the master device 102. The other detector 1 of the linked destination also outputs a voice message such as "There is a fire in the living room. There is a fire in the living room." However, the detector 1 of the fire source may output a voice message such as "It is a fire. It is a fire." In other words, the fire source detector 1 may output a voice message in which the location information is omitted.

When the detector 1 receives an operation input (pushing operation) from the outside by a push button type operation unit or the like during an alarm (while issuing an alarm sound), the acoustic unit 42 stops outputting the alarm sound. ..

The display unit 41 has a function of notifying the occurrence of fire. The display unit 41 is an operation lamp having a red LED 410 as a light source. The display unit 41 is normally turned off (when monitoring a fire), and starts blinking (or lighting) when the control unit 10 determines that a fire has occurred. This blinking stops under the control of the control unit 10 when the alarm sound is stopped.

As described above, the storage unit 20 corresponds to the holding unit H1 and is configured by a device selected from ROM, RAM, EEPROM, or the like. The storage unit 20 stores a unique identifier (identification information) assigned to itself (own device). The “identifier (identification information)” is the IP address, Mac address, or name of the detector 1. The storage unit 20 also stores warning message data related to a voice message output as a warning sound. The storage unit 20 may be the memory of the control unit 10.

In particular, the storage unit 20 (holding unit H1) of the parent device 102 is associated with the location information related to the installation place L1 where the own device is installed and the installation place L1 where the other detector 1 is installed, as described above. It stores the location information to be used. Here, the storage unit 20 stores, as location information, a plurality of pieces of code information for respectively identifying the installation locations L1 of the plurality of detectors 1 including itself, as location information, in association with the identifiers of the corresponding detectors 1. .. The location information is, for example, one of the five pieces of code information “A1” to “A5”.

The storage unit 20 (holding unit H1) further holds the correspondence information. The “correspondence relationship information” is information in which name information indicating the names of the plurality of installation locations L1 and a plurality of code information identifying the plurality of installation locations L1 are associated with each other. Specifically, the holding unit H1 holds information in which, for example, the name information "living room" and the code "A1" are associated with each other. Similarly, in the holding unit H1, the name information "bedroom" and the code "A2", the name information "stairs" and the code "A3", the name information "child's room" and the code "A4", and the name information " "Kitchen" and code "A5" hold information associated with each other. The code information is not particularly limited, but the data length of the code information is preferably smaller than the data length of the name information.

The first communication unit 21 has a communication interface for performing wireless communication with another detector 1 using radio waves in the first frequency band. The first frequency band is, for example, the 420 MHz band. The first communication unit 21 receives the detection information from the other detector 1. Moreover, the 1st communication part 21 will transmit a report instruction|indication to another detector 1 (for example, detectors 1C-1E), if detection information is received from one detector 1 (for example, detector 1B).

The “detection information” is information that informs that a fire is detected in the facility 7, and may include, for example, location information (code information), an identifier, a detection result (whether or not a fire has occurred), and the like.

The second communication unit 22 has a communication interface for performing wireless communication with the external terminal 5 using a radio wave in a second frequency band different from the first frequency band. The second frequency band is, for example, the 920 MHz band. For example, when the second communication unit 22 detects a fire, the second communication unit 22 transmits the detection information of the own device to the external terminal 5. When the first communication unit 21 receives the detection information of any of the four slaves 101 (detectors 1B to 1E), the second communication unit 22 transmits the detection information to the external terminal 5. ..

The control unit 10 determines whether or not a fire has occurred based on the detection signal output by the detection unit 3. For example, the control unit 10 determines that a fire has occurred when the voltage level indicated by the detection signal is equal to or higher than a predetermined threshold value.

Further, as shown in FIG. 1, the control unit 10 has a detection output unit 11, a setting output unit 12, a switching unit 13, and a setting unit 14. In other words, the control unit 10 has a function as the detection output unit 11, a function as the setting output unit 12, a function as the switching unit 13, and a function as the setting unit 14. The setting output unit 12, the switching unit 13, and the setting unit 14 will be described in detail later in the section “(2.5) Setting location information”.

When the self-device detects the occurrence of a fire (event), the detection output unit 11 outputs at least the location information to the output destination so that the output destination notifies the location information of the self-device. The output destinations referred to here include the four slaves 101 and the external terminal 5. That is, the detection output unit 11 outputs the detection information including the code information “A1” of its own device so that the four slave units 101 output a voice message such as “It is a fire in the living room. It is a fire in the living room.” Output to the four slaves (detectors 1B to 1E). The detection output unit 11 also outputs the detection information to the external terminal 5.

Specifically, when the self-device detects the occurrence of a fire, the detection output unit 11 sends the information notifying the fire detection, in other words, the self-device detection information via the second communication unit 22 to the external terminal 5. Send to. Further, when the self-device detects the occurrence of a fire, the detection output unit 11 sends the detection information of the self-device to four information via the first communication unit 21 in order to interlock the alarm notification as the interlocking source. It is transmitted to the child device 101.

When the control unit 10 detects the occurrence of a fire, the control unit 10 causes the sound unit 42 to start outputting an alarm sound. For example, the control unit 10 generates a voice signal corresponding to the voice message based on the message data stored in the storage unit 20, when the voice message is output from the sound unit 42 as an alarm sound. The sound unit 42 outputs a voice message (alarm sound) based on the voice signal generated by the control unit 10. In addition, the control unit 10 controls the display unit 41 so that the display unit 41 blinks when the own device detects the occurrence of a fire.

Here, when the control unit 10 detects the occurrence of a fire, the control unit 10 refers to the correspondence information in the storage unit 20, and the name information corresponding to the code information “A1” of the control unit (here, “ Search for "living room"). Then, the control unit 10 generates an audio signal including the name information “living room” and causes the audio unit 42 to notify.

On the other hand, when the control unit 10 obtains, via the first communication unit 21, information indicating that a fire in the facility 7 has been detected as detection information from any of the four slave units 101 (interlocking source), the interlocking source The detection information of No. 2 is transmitted to the external terminal 5 via the second communication unit 22. Furthermore, the control unit 10 transmits the interlocking source detection information to the other child device 101 via the first communication unit 21 in order to interlock the notification. Further, when the control unit 10 receives, as the detection information, the information indicating that the fire in the facility 7 is detected from the child device 101, the control unit 10 starts the output of the alarm sound from the sound unit 42. Further, the control unit 10 controls the display unit 41 so that the display unit 41 blinks.

Here, when the control unit 10 acquires the detection information from any of the four slaves 101, the control unit 10 extracts the code information (for example, “A2”) included in the detection information. The control unit 10 refers to the correspondence information in the storage unit 20 and searches for name information (here, “bedroom”) corresponding to “A2” that is the link source code information. Then, the control unit 10 generates an audio signal including the name information "bedroom" and causes the acoustic unit 42 to notify.

The detection information may not further include the detection result separately from the location information, and the control unit 10 determines that a fire is detected by another detector 1 triggered by receiving the location information (code information). You may. The detection information may not include the identifier. In short, the detection information is information including at least location information.

Further, since the code information is different from the identifier (identification information) unique to the detector 1, the same one code information may be assigned to two or more detectors 1. For example, if two detectors 1 are installed on the stairs, the code information of the two detectors 1 is “A3”.

(2.2.2) Handset (first detector)
Next, among the plurality of detectors 1, the configuration of four slave units 101 (detectors 1B to 1E) will be described. Hereinafter, the same components as those of the parent device 102 (detector 1A) will be denoted by the same reference numerals as those of the parent device 102, and the description thereof will be appropriately omitted.

Similar to the parent device 102, each child device 101 is configured to detect that an event (here, a fire) targeted for disaster prevention has occurred. Each child device 101 has a detection function for detecting the occurrence of a fire in the facility 7, and an alarm function for notifying when a fire is detected in the facility 7.

Similar to the parent device 102, each child device 101 includes the control unit 10, the storage unit 20 (holding unit H1), the first communication unit 21, the second communication unit 22, the battery 23, the detection unit 3, and the notification unit 4. It is equipped (see FIG. 1). In addition to this, the handset 101 further includes circuit modules such as an acoustic circuit and a lighting circuit.

However, the second communication unit 22 is not an essential component for the child device 101 and may be omitted. Alternatively, for example, when the detector 1 having the same configuration can be set to either the slave unit 101 or the master unit 102 according to a switching operation to a switch or the like, the detector 1 set to the slave unit 101. May have the function of the second communication unit 22 or may not be used.

The installation locations L1 of the four child devices 101 are a bedroom (space E2), stairs (space E3), a child's room (space E4), and a kitchen (space E5), respectively.

The storage unit 20 of each child device 101 corresponds to the holding unit H1 and is configured by a device selected from ROM, RAM, EEPROM, or the like. The storage unit 20 stores a unique identifier (identification information) assigned to itself (own device). The storage unit 20 also stores warning message data related to a voice message output as a warning sound.

Unlike the storage unit 20 of the parent device 102, the storage unit 20 of each child device 101 stores only the location information related to the installation location L1 where the own device is installed, and another detector 1 is installed. The location information related to the installation location L1 is not stored. In other words, the place information held by the holding unit H1 of the child device 101 is information related only to the installation place L1 of the own device.

The control unit 10 of each child device 101 includes a detection output unit 11, a setting output unit 12, a switching unit 13, and a setting unit 14. In other words, the control unit 10 has a function as the detection output unit 11, a function as the setting output unit 12, a function as the switching unit 13, and a function as the setting unit 14. The setting output unit 12, the switching unit 13, and the setting unit 14 will be described in detail later in the section “(2.5) Setting location information”.

When the self-device detects the occurrence of a fire (event), the detection output unit 11 outputs at least the location information to the output destination so that the output destination notifies the location information of the self-device. The output destination mentioned here includes the master device 102. For example, when the detector 1B detects the occurrence of a fire, the detection output unit 11 of the detector 1B causes the master unit 102 to output a voice message such as "A fire in the bedroom. A fire in the bedroom." The detection information including the code information “A2” of the own device is output to the parent device 102. In addition, the detection output unit 11 outputs the detection information including the code information “A2” of the own device so that the other three child devices 101 also output a voice message such as “It is a fire in the bedroom. It is a fire in the bedroom.” , To the other three slave units 101 via the master unit 102. In other words, the detection output unit 11 of each child device 101 detects the occurrence of a fire via the first communication unit 21 in order to serve as an interlocking source and interlock the alarm when the own device detects the occurrence of a fire. The information is transmitted to the master device 102.

The control unit 10 of each child device 101 causes the sound unit 42 of the own device to start outputting an alarm sound when the own device detects the occurrence of a fire. Moreover, the control part 10 of each cordless handset 101 controls the display part 41 so that the display part 41 of the self-opportunity may blink, when a self-device detects the occurrence of a fire.

Here, when the control unit 10 of each child device 101 detects the occurrence of a fire, the control unit 10 refers to the correspondence information in the storage unit 20 of the own device to obtain the name information corresponding to the code information of the own device. Search for. Then, the control unit 10 generates an audio signal including the name information and causes the audio unit 42 of the own device to notify it.

On the other hand, when the control unit 10 of each child device 101 obtains the detection information notifying that the fire of the facility 7 is detected from the parent device 102 via the first communication unit 21, the controller 10 of the child device 101 issues an alarm from the acoustic unit 42 of the own device. Output sound. Further, the control unit 10 controls the display unit 41 so that the display unit 41 of the own device blinks.

Here, when the control unit 10 of each child device 101 acquires the detection information from the parent device 102, the control unit 10 extracts the code information included in the detection information. In this case, the code information is any code information of the four detectors 1 other than the own device. The control unit 10 refers to the correspondence information in the storage unit 20 of its own device and searches for the name information corresponding to the code information of the link source (fire source). Then, the control unit 10 generates an audio signal including the name information and causes the audio unit 42 of the own device to notify it.

(2.3) External Terminal The external terminal 5 (control device) is, for example, a controller of a HEMS (home energy management system) as described above, and can communicate with a plurality of devices provided in the facility 7. The plurality of devices may include, for example, an air conditioner, a water heater, and the like. In the present embodiment, the external terminal 5 can further communicate with the parent device 102 (detector 1A) provided in the facility 7.

As shown in FIG. 1, the external terminal 5 includes a control unit 50, a communication unit 53, a storage unit 54, a display unit 55, and the like.

The control unit 50 has, for example, a computer system having a processor and a memory. Then, the computer system functions as the control unit 50 by the processor executing the program stored in the memory. The program executed by the processor is previously recorded in the memory of the computer system here, but may be provided by being recorded in a recording medium such as a memory card or through a telecommunication line such as the Internet. ..

The communication unit 53 includes a first (communication) interface 53A for communicating with the parent device 102 and the like. The first interface 53A receives various information from the base unit 102 and the like by wireless communication using radio waves in the second frequency band (for example, 920 MHz band). The communication unit 53 also has a second (communication) interface 53B for communicating with the information terminal 6 and the external server 8 via the network NT1 (see FIG. 3) such as the Internet. The second interface 53B may communicate with the information terminal 6 via another device such as the external server 8. The information terminal 6 is a smartphone, a tablet terminal, or the like owned by a user (for example, a resident) of the facility 7. In this embodiment, the information terminal 6 is assumed to be a smartphone. On the information terminal 6, dedicated application software that enables wireless communication with the external terminal 5 is installed.

The storage unit 54 is composed of a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like.

The storage unit 54 stores an identifier (identification information) of each of the plurality of detectors 1 or the like. The storage unit 54 stores each of the plurality of detectors 1 and the installation location L1 (any of the spaces E1 to E5) where the corresponding detector 1 is installed in association with each other. Specifically, the storage unit 54 stores, for example, the identifier of the detector 1A and the place information (code information) related to the installation place L1 (space E1) of the detector 1A in association with each other. Similarly, the storage unit 54 associates the identifiers of the detectors 1B to 1E with the location information (code information) related to the installation location L1 (spaces E2 to E5) of the detectors 1B to 1E in a one-to-one correspondence. Remember. In addition to this, the storage unit 54 also stores correspondence information commonly stored in the storage unit 20 of each detector 1 and information (for example, a telephone number) regarding the information terminal 6.

As shown in FIG. 1, the control unit 50 has an acquisition unit 51, a registration unit 52, and the like. In other words, the control unit 50 has a function as the acquisition unit 51 and a function as the registration unit 52.

The acquisition unit 51 is configured to acquire the detection information of the plurality of detectors 1 from the parent device 102. Specifically, when any of the detectors 1 detects a fire, the acquisition unit 51 acquires the detection information from the master device 102 via the first interface 53A. The control unit 50 may cause the display unit 55 to display the location information (name information) related to the installation location L1 of the detector 1 that is the fire source, based on the acquired detection information. If the external terminal 5 has the map information (floor map, etc.) of the facility 7, it may be displayed together with the map information so that the installation location L1 of the detector 1 as the fire source can be known. If the external server 8 is a server device managed by a security company or the like, the external terminal 5 may notify the external server 8 that a fire has occurred, based on the acquired detection information. The external terminal 5 may also notify the information terminal 6 that a fire has occurred, based on the acquired detection information.

Further, the acquisition unit 51 is configured to acquire the location information from the information terminal 6. The acquisition unit 51 acquires the location information via the second interface 53B according to the operation input to the information terminal 6. The registration unit 52 registers the location information received from the information terminal 6 and the identifier of the detector 1 in the storage unit 54 in association with each other.

Specifically, the external terminal 5 responds to a request received from the application software running on the information terminal 6 such as the identifier of the detector 1 which is currently installed or is about to be installed (if it is being installed, the Name information such as “” may be output to the information terminal 6. The resident refers to the list of the identifiers and the like of the detectors 1 presented on the display screen of the information terminal 6 and inputs operation regarding new addition, change, deletion, etc. of the location information corresponding to each detector 1. May be able to do.

If the external terminal 5 holds the map information (floor map, etc.) of the facility 7, the external terminal 5 may associate the identifier of the detector 1 with the map information and present the same on the display screen of the information terminal 6. .. The resident may perform an operation input regarding new addition, change, deletion, etc. of the location information corresponding to the detector 1 by tapping a mark simulating the detector 1.

The registration unit 52 associates the location information with the identifier of the detector 1 and registers (newly adds, changes, or deletes) the storage unit 54 in association with each other in accordance with the operation input from the information terminal 6. The external terminal 5 outputs the registered information to the master device 102 via the first interface 53A in order to reflect the registered information in the storage unit 20 of the master device 102 as well.

Since the external terminal 5 has the acquisition unit 51 and the registration unit 52, the user can register the location information of the detector 1 with respect to the external terminal 5 from the information terminal 6.

The external terminal 5 also manages the correspondence information that is commonly stored in the storage unit 20 of each detector 1. The external terminal 5 may output the correspondence information in response to a request received from the application software running on the information terminal 6. Even if the resident can perform operation input regarding new addition, change, deletion, etc. of the name information corresponding to each code information while referring to the correspondence information presented on the display screen of the information terminal 6. Good. For example, when the code information "A1" and the name information "living room" are associated in the correspondence information, the name information corresponding to the code information "A1" can be changed from "living room" to "kitchen". It may be. Alternatively, the correspondence relation of the code information “B1” and the name information “entrance” may be newly added to the correspondence relation information. The name information may be changed to “Room of XX” (where XX is the name of the resident's child, etc.) according to the preference of the resident, or the language may be changed from Japanese to English. May be.

The external terminal 5 outputs the changed correspondence information to the master device 102 via the first interface 53A in order to reflect the changed correspondence information in the storage unit 20 of the master device 102. In addition, the master device 102 outputs the changed correspondence information to all the slave devices 101 via the first communication unit 21 in order to reflect the changed correspondence information in the storage unit 20 of the slave device 101.

All the information such as the identifier, the correspondence information, the map information, the code information, and the name information described above is not limited to being stored and managed only in the storage unit 54 of the external terminal 5. Part or all of this information may be stored in the storage unit of the external server 8, for example. The external server 8 may manage this information for each facility 7. The administrator who manages the external server 8 designates the facility 7 and changes the settings of the above-mentioned identifier, correspondence information, map information, code information, name information, etc. for the external terminal 5 of the facility 7. May be performed.

The display unit 55 is, for example, a thin display device such as a liquid crystal display or an organic EL (electroluminescence) display. The display unit 55 may display the information and the like acquired by the acquisition unit 51.

The external terminal 5 uses the operation unit provided in the casing of the external terminal 5 for the above-mentioned new addition, change, deletion, etc. of the location information corresponding to each detector 1, and the change of the correspondence information. It may be performed by the operation input of. If the display unit 55 is a touch panel type display device, it may also have the function of the operation unit.

(2.4) Operation The operation of the detector management system 200 when a fire is detected will be briefly described below.

[Operation example 1]
First, the operation of the detector management system 200 when the parent device 102 (detector 1A) detects a fire will be described with reference to FIG.

Master device 102 detects a fire (step ST1). The base unit 102 makes a notification according to the location information of its own unit. That is, the master device 102 refers to the correspondence information in accordance with the code information “A1” that is the location information of its own device, and refers to the correspondence information, and outputs the voice message “The living room is a fire. Is continuously output to the sweep sound (step ST2). As described above, the voice message output from the base unit 102 of the fire source may simply be "fire. Fire.".

The master device 102 also transmits the detection information to the other four slave devices 101 from the first communication unit 21 that performs wireless communication using radio waves in the first frequency band (for example, 420 MHz band) (step ST3). However, in FIG. 4, only one of the four slave units 101 is illustrated. Receiving the detection information, each child device 101 extracts the code information “A1” included in the detection information, and refers to the correspondence information in the storage unit 20 of the own device to correspond to the code information “A1”. The name information “living room” to be determined is determined. Then, each slave unit 101 outputs the voice message “Fire in the living room. Fire in the living room.” in succession to the sweep sound in synchronization with the notification from the base unit 102 (step ST4).

Furthermore, the master device 102 transmits the detection information to the external terminal 5 by the second communication unit 22 that performs wireless communication using radio waves in the second frequency band (for example, 920 MHz band) (step ST5). The external terminal 5 displays on the display unit 55 that a fire has occurred in the living room (space E1) of the facility 7 based on the received detection information, and also notifies the information terminal 6 and the external server 8 (step). ST6).

According to this, the parent device 102 causes the child device 101, which is the output destination of the detection information, to perform notification according to the location information of the own device. Therefore, it is possible to further improve the recognizability of the place where the fire occurs. That is, it is possible to increase the possibility that the user can quickly recognize the fire source from the alarm content of the detector 1.

[Operation example 2]
Next, the operation of the detector management system 200 when any of the four slave units 101 (detectors 1B to 1E) detects a fire will be described with reference to FIG. Here, as an example, it is assumed that the detector 1E installed in the kitchen detects a fire.

The detector 1E, which is the child device 101, detects a fire (step ST11). The detector 1E gives notification according to the location information of its own device. That is, the detector 1E refers to the correspondence information according to the code information "A5" that is the location information of the own device, and refers to the correspondence information, and the voice message "It is a fire in the kitchen. It is a fire in the kitchen. Is continuously output to the sweep sound (step ST12). As described above, the voice message output from the fire source detector 1E may simply be "fire. Fire."

Further, the detector 1E transmits the detection information to the master device 102 by the first communication unit 21 that performs wireless communication using radio waves in the first frequency band (for example, 420 MHz band) (step ST13). Upon receiving the detection information, the parent device 102 extracts the code information “A5” included in the detection information, and refers to the correspondence information in the storage unit 20 of the own device to correspond to the code information “A5”. Name information "Kitchen" is decided. The main|base station 102 is linked with the alerting|reporting of the detector 1E, and outputs the voice message "It is a fire in the kitchen. It is a fire in the kitchen." continuously in a sweep sound (step ST14).

Further, the master device 102 transmits the detection information to the other three slave devices 101 (detectors 1B to 1D) by the first communication unit 21 that performs wireless communication using radio waves in the first frequency band (for example, 420 MHz band). Yes (step ST15). Based on the received detection information, the three child devices 101 (detectors 1B to 1D) continuously output the voice message "I have a fire in the kitchen. I have a fire in the kitchen." in the sweep sound (step ST16). However, in FIG. 5, only one of the three slave units 101 is illustrated.

Further, the master device 102 transmits the detection information to the external terminal 5 by the second communication unit 22 that performs wireless communication using radio waves in the second frequency band (for example, 920 MHz band) (step ST17). Based on the received detection information, the external terminal 5 displays on the display unit 55 that a fire has occurred in the kitchen (space E5) of the facility 7, and also notifies the information terminal 6 and the external server 8 of the like (step ST18).

Accordingly, the child device 101 causes the parent device 102, which is the output destination of the detection information, and the other child device 101 to perform notification according to the location information of the own device. Therefore, it is possible to further improve the recognizability of the place where the fire occurs. That is, it is possible to increase the possibility that the user can quickly recognize the fire source from the alarm content of the detector 1. Further, since the parent device 102 includes both the first communication unit 21 and the second communication unit 22, the information on the child device 101 side can be easily sent to the external terminal 5. In particular, between the slave 101 (first detector) and the external terminal 5 that use different frequency bands in wireless communication, when the slave 101 detects the occurrence of a fire, the location information of the slave 101 is used as the external terminal 5 information. You can easily send to.

By the way, in the present embodiment, the storage unit 20 (holding unit H1) of each child device 101 stores only the location information of its own device and does not store the location information of other devices. Therefore, when newly installing a plurality of detectors 1 or adding one or a plurality of detectors 1, it is possible to save the trouble of storing the location information of all the detectors 1 in one child device 101. It is possible to reduce the work load related to setting location information. In other words, for each detector 1, it is not necessary to manage in advance where the other detector 1 is installed and what identifier it is, and the time when the fire actually occurs does not have to be managed in advance. All that is necessary is to make a notification according to the location information received in.

(2.5) Setting of Place Information Hereinafter, the setting output unit 12, the switching unit 13, and the setting unit 14 in the control unit 10 of each detector 1 will be described together with the operation related to the setting of place information.

First, setting of the location information for each detector 1 will be described.

The switching unit 13 is one of a plurality of operation modes including at least a detection mode for detecting the occurrence of a fire (event) and a setting mode for setting location information for the storage unit 20 (holding unit H1). Is configured to switch to. The operation mode may include, for example, an operation test mode for inspection in addition to the detection mode and the setting mode. The switching unit 13 sets the operation mode from the detection mode in accordance with, for example, a simultaneous push operation on two push button type operation units (which may be dip switches or the like) exposed from the housing of each detector 1. Switch to mode.

In each detector 1, when the operation mode is switched to the detection mode, the control unit 10 monitors whether or not a fire has occurred. When a fire is detected, the detector 1 executes the operation described in the above section “(2.4) Operation”.

On the other hand, in each detector 1, when the operation mode is switched to the setting mode, the setting unit 14 receives the setting of the location information for the storage unit 20 (holding unit H1). In this case, the setting unit 14 receives, for example, one piece of candidate information as a piece of location information from among a plurality of pieces of predetermined piece of candidate information representing a place to be installed. Specifically, a plurality of pieces of candidate information such as the living room, stairs, entrance, self-service entrance, kitchen, washroom, toilet, bedroom, children's room, etc. are stored in advance in the storage unit 20 of each detector 1. The plurality of pieces of candidate information are stored in the storage unit 20 in a one-to-one correspondence with the plurality of pieces of code information. In short, the plurality of name information in the above-mentioned “correspondence information”, which is commonly stored in the storage unit 20 of each detector 1, corresponds to the plurality of candidate information referred to here.

For example, each time the user presses one of the two operation units of each detector 1 once, the candidate information is changed from the first candidate information (living room in the above example) to the ninth candidate information (in the above example, in the above example). Voice messages are output in ascending order toward the children's room. In addition, each time the user presses the other of the two operation units once, the candidate information is output in the descending order as a voice message. In other words, the setting unit 14 causes the acoustic unit 42 to sequentially output a plurality of name information items in the above-described “correspondence information” in the form of voice messages in response to the user's pressing operation on the operation unit.

When the voice message of the candidate information desired by the user is output, the candidate information is determined as the location information of the detector 1 by simultaneously pressing the two operation units again, and the operation mode is further determined. However, the setting mode is switched to the detection mode. The control unit 10 stores the code information corresponding to the candidate information (name information) in the storage unit 20 as the location information of the own device. The control unit 10 may store the name information as it is as the location information of the own device.

In the present embodiment, since each detector 1 includes the switching unit 13 and the setting unit 14, the location information is set for each detector 1 according to the user's request or the installation environment of the detector 1. can do. In particular, since the setting unit 14 accepts the setting of one piece of candidate information as the place information from a plurality of predetermined pieces of candidate information, the user can select the place information from the plurality of pieces of candidate information. As a result, it is possible to improve workability regarding the work of setting the location information in each detector 1.

Next, registration of the location information of each detector 1 with respect to the external terminal 5 will be described.

When the setting unit 14 of the own device receives the setting of the location information, the setting output unit 12 causes the external terminal 5 to register the location information of the own device and the identification information of the own device in association with each other. It outputs the location information and identification information of the machine. Here, the output destination of the location information and the identification information in each detector 1 differs depending on whether the own device is the slave device 101 or the master device 102.

When the setting unit 14 of its own device receives the setting of the location information, the parent device 102 (second detector) sends the location information and identification information of the own device to the outside by the second communication unit 22 of the own device. Output to the terminal 5.

When each slave unit 101 (first detector) receives the setting of the location information in the setting unit 14 of the own unit, the location information and the identification information of the own unit are transmitted by the first communication unit 21 of the own unit, Output to the master unit 102. Then, the master device 102 outputs the location information and the identification information received from the slave device 101 to the external terminal 5 by the second communication section 22 of the master device 102. The parent device 102 also registers the location information and the identification information received from the child device 101 in the storage unit 20 of its own device.

On the other hand, when the external terminal 5 receives the location information and the identification information of the detector 1 from the parent device 102 via the first interface 53A, they are associated with each other and registered in the storage unit 54. The external terminal 5 may send the location information and identification information of the detector 1 to the external server 8.

In short, when the user sets the location information of the mobile device 101, the mobile device 101 registers the location information of the mobile device and the identification information of the mobile device in the external terminal 5 in association with each other via the master device 102. Let

In this embodiment, each detector 1 includes a setting output unit 12. Therefore, when the slave 101 receives the setting of the location information between the slave 101 (first detector) and the external terminal 5 that use different frequency bands in wireless communication, the location information of the slave 101 is transferred to the outside. It can be easily sent to the terminal 5. In other words, it is possible to improve workability regarding the work of registering the location information of the detector 1 in the external terminal 5. Further, it is possible to cause the external terminal 5 to manage the plurality of detectors 1.

(3) Modifications The above embodiment is only one of the various embodiments of the present disclosure. The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. Further, the same function as that of the detector 1 according to the above-described embodiment may be embodied by a control method of the detector 1, a computer program, a non-transitory recording medium recording the computer program, or the like.

Hereinafter, modified examples of the above embodiment will be listed. The modifications described below can be applied in appropriate combination. Hereinafter, the above embodiment may be referred to as a “basic example”.

The control unit 10 of the detector 1 and the control unit 50 of the external terminal 5 according to the present disclosure include a computer system. The computer system mainly has a processor and a memory as hardware. The functions of the control unit 10 of the detector 1 and the control unit 50 of the external terminal 5 according to the present disclosure are realized by the processor executing the program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or recorded in a non-transitory recording medium such as a memory card, an optical disk, a hard disk drive, etc. that can be read by the computer system. May be provided. The processor of the computer system is composed of one or a plurality of electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuit such as IC or LSI referred to here is called differently depending on the degree of integration, and includes an integrated circuit called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, an FPGA (Field-Programmable Gate Array) that is programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the connection relation inside the LSI or reconfiguring the circuit section inside the LSI should also be adopted as a processor. You can The plurality of electronic circuits may be integrated in one chip, or may be distributed and provided in the plurality of chips. The plurality of chips may be integrated in one device, or may be distributed and provided in the plurality of devices. The computer system referred to herein includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or a plurality of electronic circuits including a semiconductor integrated circuit or a large scale integrated circuit.

In addition, the fact that a plurality of functions in each of the detector 1 and the external terminal 5 are integrated in one housing is not an essential configuration of the detector 1 and the external terminal 5, but the detector 1 and the external terminal 5 are integrated. Each component may be provided dispersedly in a plurality of housings. Furthermore, at least a part of the functions of the detector 1, for example, a part of the functions of the detector 1 may be realized by a cloud (cloud computing) or the like. Similarly, at least a part of the functions of the external terminal 5, for example, a part of the functions of the external terminal 5 may be realized by a cloud or the like. On the contrary, as in the basic example, the plurality of functions of the detector 1 may be integrated in one housing, and the plurality of functions of the external terminal 5 may be integrated in one housing.

In the basic example, the storage unit 20 (holding unit H1) of each detector 1 holds the correspondence information. However, the correspondence information is not essential, and the storage unit 20 of each detector 1 may not hold the correspondence information. Specifically, in the basic example, when a fire is detected, the location information of the detection information transmitted/received between the child device 101 and the parent device 102, and between the parent device 102 and the external terminal 5 includes the code information. Including. However, instead of transmitting/receiving the code information as the location information, the name information indicating the name of the installation location L1 may be directly transmitted/received as the location information. Alternatively, the detection information may include, as the location information, a voice signal corresponding to a voice message such as “A fire in the living room. A fire in the living room.” which is actually output from the acoustic unit 42 of the detector 1 of the linked destination. .. However, as in the basic example, the configuration in which the storage unit 20 of each detector 1 holds the correspondence information and the code information is transmitted and received as the location information reduces the information amount (data length) related to the location information. be able to. In particular, when the detector 1 is of a battery type, it is possible to reduce the power consumption of the battery 23 by suppressing the data length.

Further, some of the plurality of detectors 1 may hold the correspondence information, and the remaining detectors 1 may not hold the correspondence information. In this case, when the detector 1 which does not hold the correspondence information receives the detection information including the code information, the control unit 10 of the detector 1 "fires in another room. Fires in another room" A voice message such as "." may be output from the sound section 42.

In the basic example, each of the detectors 1 is a living policing device that includes a notification unit 4 and has a function (a notification function) of outputting a warning sound to notify the occurrence of a fire. However, the notification unit 4 is not an essential component for each detector 1. At least one of the plurality of detectors 1 may not have the function of reporting the occurrence of a fire. At least one of the plurality of detectors 1 may only transmit the detection information to another device when detecting the occurrence of a fire.

In the basic example, the storage unit 20 (holding unit H1) of the parent device 102 holds not only the location information of its own device but also the location information of another device (child device 101). However, the storage unit 20 of the parent device 102 may also hold only the location information of its own device and not the location information of the other device (child device 101). However, it is desirable that the master device 102 manages (stores) at least the number of slave devices 101 and the identifier of each slave device 101.
